Face Recognition Redemption for Secure Value Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face security risks and inconvenience when transferring value, such as gift cards, due to physical loss or theft, and electronic methods require managing identifiers for redemption.
Innovation Solution
A method utilizing face-recognition technology for value transfer, where a first user's image data is received and stored, and authorization is granted based on matching with stored biometric data, allowing secure and convenient transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical gift cards are used for value transfer, then value can be transferred to users, but security risks increase due to potential loss or theft
Solution Approach 1:
The patent replaces physical gift cards with digital copies stored as biometric templates in a database. The physical card is replaced by its digital representation, which cannot be lost or stolen in the same way. The system stores encrypted biometric templates and uses them for authentication, eliminating the need for physical carriers that can be misplaced or stolen.
Solution Approach 2:
The patent substitutes the mechanical physical card system with a biometric authentication system. Instead of using physical cards that can be lost or stolen, the system uses facial recognition and other biometric data to authenticate users. This replacement of mechanical/physical mechanisms with biological/digital mechanisms significantly improves security while maintaining the value transfer function.
2Ease of operation
If electronic gift cards with identifiers are used, then value transfer is convenient, but users must manage and track identifiers for redemption
Solution Approach 1:
The system performs self-service by automatically matching the user's biometric data with the stored template during redemption. The user simply presents their face or other biometric characteristic, and the system automatically identifies them and processes the redemption without requiring them to manually enter or track identifier numbers. This eliminates the burden of managing and tracking identifiers.
Solution Approach 2:
The patent replaces the electronic identifier tracking system with a biometric authentication system. Instead of requiring users to remember, write down, or track gift card numbers and codes, the system uses biological characteristics (face, fingerprint, iris) for authentication. This substitution eliminates the information management burden while maintaining convenient access to value.
3Reliability
If biometric templates are stored for authentication, then secure value transfer is achieved, but data storage and processing complexity increases
Solution Approach 1:
The patent extracts only the essential biometric features from the full image data and stores compressed templates. Instead of storing complete facial images or complex biometric datasets, the system extracts key identifying characteristics and stores simplified templates that are sufficient for authentication. This extraction reduces storage requirements and processing complexity while maintaining security.
Solution Approach 2:
The system changes the parameters of biometric data through encryption, compression, and transformation. Biometric templates are encrypted and stored in a format optimized for comparison rather than full image storage. The system uses hashed and processed versions of biometric data, reducing the amount of raw data that needs to be stored and processed while maintaining authentication capability.
Data Source
AI summary
A system and method are provided which include receiving, from a first user, first image data of a second user and a request to provide a value for the second user; storing the first image data of the second user in association with the value; transmitting, to the second user, a notification that the value is available; receiving, from an access device, an authorization request message comprising access data and second image data of the second user; determining a result based on (a) whether the first image data of the second user matches the second image data of the second user and (b) the stored value; and transmitting, to the access device, an authorization response message comprising the result.
